Effects of the LRM on respiratory mechanics and gas exchanges, as a function of the patients’ lung recruitability. Effects of LRM on PaO2/FiO2 and ventilator ratio (A, B), end-expiratory and end-inspiratory transpulmonary pressures (C, D), and pulse pressure and heart rate (E, F). Patients with low lung recruitability (red circles) and high lung recruitability (blue squares) were defined by an R/I below or above the median value for the cohort (0.62). HR: heart rate, PaO2/FiO2: partial pressure of oxygen to inspired oxygen fraction, PL,EE: transpulmonary pressure at end-expiration, PL,EI: transpulmonary pressure at end-inspiration, PP: pulse pressure, R/I: recruitment-to-inflation ratio, VR: ventilator ratio
